I think Dufty has to bulk up before he comes back to first grade. Other teams drag him like a rag doll. He has great potential but he needs the size to cope with the week in week out riggers of the NRL.
Size would help for sure.
Slater and others showed it’s not essential though. Technique is what the smaller guys need to master (through coaching and experience).
He rarely gets rag dolled in a one on one situation (except his first few games). Most of the time Dufty get’s rag dolled is when a second and third (bigger) defender get involved and that can be mitigated with help from supporting players and positioning as was often displayed with Slater and others.
Coaching would also help as has been displayed in Bennet/Soward, Bennett/Langer/Lockyer days.
I just think Dufty’s stillour most promising back and we’d be crazy to play against him, because he’d do our other backs in a blink of the eye.
